ImgTarget

ImgTarget is a front-end to functionality provided by ArgyllCMS - specifically the tiffgamut and collink utilities. These utilities are capable of building a custom devicelink colour profile tailored to achieve the best possible rendition for a specific image.

ImgTarget wraps the details of performing this task in a graphical user interface, and displays the original image, the image converted to a specific profile the traditional way, and the results of applying the devicelink profile - all side-by-side for convenient comparison. It can also export the converted image data, with the target profile embedded, in either TIFF or JPEG format.

Why?

To understand the problem ImgTarget is intended to solve, we must first look at how a traditional colour-managed workflow operates.

The range of colours (gamut) a typical printer can produce is somewhat smaller than that of an RGB "working space" such as sRGB, AdobeRGB, or especially the various wide-gamut RGB spaces such as ProPhotoRGB. Given an ICC colour profile for a working space and for a printer, a traditional colour management system will build a transform between the two colourspaces, compressing the colours to fit the printer's limited range.
